The highest quality and highest concentration organic calcium for amending soil and top feeding and/or fixing calcium deficiency. Jeremy and the team are extremely helpful and go out of their way to help their customers and make sure we are happy campers. If you haven't tried BuildASoil nutrients and soil and other products then you are in for a treat and once you try them, you'll never go back. I've done synthetic grow, liquid and powder organic nutrients even living soil with low quality ingredients but did not get the results I was after until I tried BuildASoil nutrients and soil and it took my grow to a whole other level. Super happy and highly recommend! Stay lit! 🗣️💨

High quality organic calcium! But wear a mask, very fine dust.....

This is very fine, so just take precaution for the airborne particles. This oyster shell flour is a great source of calcium, small amounts go a long way. Use to reamend your old soil or as a top feed during your grow.
